Ahead of the initial public offering, Brean analysts rated the stock a "Buy" and wrote: "We give Etsy a score of 87 out of 100 for our investment framework of the six key areas necessary to be successful in the future of retail (social, international expansion, mobile, payments, logistics, and enabling technology)."

Netflix also had a huge day, rallying by more than 18% to an all-time high of $568.75 per share. On Wednesday, the company reported first quarter results, which showed it added 2.28 million US subscribers and 2.6 million international subscribers, smashing forecasts. Analysts at FBR & Co. hiked their price target to $900, reflecting a nearly 70% upside from where it was priced pre-market; that was one of several upgrades by analysts today.

Pacira Pharmaceuticals tanked by as much as 12% to the lowest level in 10 months after it disclosed a subpoena from the Department of Justice.

Pacira has a market cap of around $3 billion. It said it will cooperate with the DoJ.
